gradually grow and expand. D. Wardianum should be kept back more 

 than any other, and not allowed to flower before March, if possible. There 

 are some few Dendrobes which are never really at rest, but are continually 

 growing. Such as D. sanguinolentum, D. X rhodostoma, D. Dearei, 

 D. Hookerianum, and D. Maccarthiae. These, and other similar kinds, 

 should be allowed to grow gently on, and not be rested in the same way as 

 the others. 



The pretty little Sophronitis grandiflora will soon expand its bright 

 coloured blossoms. I have previously advised a slightly warmer temperature 

 than that afforded in the coolest house for this, which is well suited in a 

 shady and very moist house. The species of Sophronitis do not take well 

 to root disturbance, but re-potting has to be done occasionally. Small pans 

 or bafkets are the best, and re-potting should take place as soon as the 

 flowers have faded. 



In the East Indian House, the Phalsenopsis will be pushing flower 

 spikes, but careful watering here must prevail. It is, no doubt, thought 

 sometimes that Orchids like these, having no pseudobulbs, cannot success- 

 fully withstand so much drought as those which have. Doubtless this is 

 true, yet it is remarkable what a little water is really necessary for the 

 wants of pseudobulbless Orchids during the winter or resting season. 

 They should not be dipped or otherwise soaked with water, a slight surface 

 wetting, and the sides of the receptacles moistened occasionally, being the 

 safest plan. The spikes should not be allowed to remain on too long, 

 especially on small weakly plants, as nothing tends to weaken their 

 constitution so much as over-flowering. The safest plan is to cut off the 

 spikes immediately the terminal bud has opened. 



Winter Treatment of Bolleas.— Speaking of the winter treatment 

 of certain Orchids in the Journal of Horticulture, " H. R. H." remarks 

 that those restless plants, the Pescatoreas, Bolleas, Huntleyas, and 



They seem to delight in a regular and constantly moist house all through 

 the year, where the temperature never rises much above 75deg. or falls below 

 6odeg. In summer they delight in a broken light rather than a dense 

 shade, but now they need every ray of light they can get, and in 

 consequence must be arranged near the glass, this in its turn being kept 

 perfectly clear. They are very subject to red spider attacks, which turn 

 the bright green foliage a pale sickly hue, consequently the sponge must be 

 freely used. It is too late now to repot them, and if the moss has grown 

 too strongly about the roots, a little of it should be removed, as it is apt 

 to become sodden from the atmospheric moisture-
